I do not play in android mode, only on the pc and for me on the pc I have used to save the game when there are multiple dialog choices.
I have the impression that the author of the game, leaves several options for answers, and only one is real... but there are very good sex scenes in my opinion.
There are even animated pregnancy risk scenes
My personal assessment is that it is a good game, with a good story with hints of very intelligent humor.
In general I liked the game, although the multiple choices can take you longer to find the scenes that really matter.
I recommend it, maybe you as I might even like Who's the father as I did.
